how can communicate oracle database python code assuming database run on windows server 2008 ? can communicate on other os windows xp / windows server 2003 / ... using oracle provider ole db ( http://www.oracle.com/technetwork/database/windows/utilsoft-088126.html ) none of them seem support windows server 2008. may ask hints? you can user cx_oracle module connect oracle python. how user python oracle? http://www.oracle.com/technetwork/articles/dsl/python-091105.html where documentation cx_oracle? http://cx-oracle.sourceforge.net/html/index.html this may solve problem.

i need introspection in numpy/scipy. while relatively easy find info on how docstring , arguments, not able concerning how info on returned values. more specifically, find functions return multiple values, or equivalently (more or less) tuples. way it? there no way can find out python in general. answer not constant. def complicated(i): if == 1: return 0 elif == 2: return (0,1) elif == 3: return [0,1,2] elif program_halts(i): return {} else return "nope" what worse, if know inputs, can't tell result without solving halting problem. your chance read documentation.

suppose have def f() = (1, 2, 3) somewhere in code call it: val (a, b, c) = f() but can confused multiple assignments: val a, b, c = f() // here every variable == (1, 2, 3) moreover, have never used multiple assignments feature. reasons above think it's harmful. possible make compiler warn on it? the direct answer question no. said, if want build compiler plugin this, can achieve goal of issuing warning. said, how build compiler plugin beyond scope of answer here.

i'm wanting know elastic search. said helps search data when see webinars feels have replicate data in kind of elastic datastore... not means otpimized me. in way modification done on left hand have reported on right hand , data returned elastic search may not in right format. can elastic search can directly search in database? it's use neo4j graph database. did that? replace cypher queries? thanks advices, helping me on realize on elastic search can helps on our project. elasticsearch is database, it's not relational database may used to. nosql database. you insert json documents index. query index find documents match particular criterion. it sharded , node distributed, gives resilience , scalability, , - if set right - performance. this means it's @ 'search engine' style database queries, because it's not relational, cannot equivalent of sql join operation easily. one example use case logstash , kibana - known elk stack - system

whenever start having bigger number of classes (1000 , more) multinominalnb gets super slow , takes gigabytes of ram. same true scikit learn classification algorithms support .partial_fit() (sgdclassifier, perceptron). when working convolutional neural networks 10000 classes no problem. when want train multinominalnb on same data 12gb of ram not enough , very slow. understanding of naive bayes, lot of classes, should lot faster. might problem of scikit-learn implementation (maybe of .partial_fit() function) ? how can train multinominalnb/sgdclassifier/perceptron on 10000+ classes (batchwise)? short answer without information: the multinomialnb fits independent model each of classes, thus, if have c=10000+ classes fit c=10000+ models , therefore, model parameters [n_classes x n_features] , quite lot of memory if n_features large. the sgdclassifier of scikits-learn uses ova (one-versus-all) strategy train multiclass model (as sgdc not inherently multiclass) , therefo

so have page on button click, image added embellishments after performing various calculations on meta-data stored data-attributes. since calculations can take few seconds, want show overlay on image. do: $(selectedimageid).addclass('loading'); //perform series of calculations here... $(selectedimageid).removeclass('loading').addclass('calculated-embellishments'); i imagine script first show loading overlay on image, perform lengthy calculations, replace overlay selected embellishment class. seems dom updated @ end such never see loading class, directly jumps plain image embellishment class after few seconds. if add alert('test') before last line adds embellishment can see loading overlay on image, not otherwise. how can make work way want to, explained above? pointers welcome! what happens " lengthy calculations " make browser "hang" processing, not having chance re-paint image reflect newly added loading cla

how small should table using diststyle in amazon redshift? it says here: http://dwbitechguru.blogspot.com/2014/11/performance-tuning-in-amazon-redshift.html vey small tables, redshift should use diststyle instead of or key. how small small? if specify row number in clause of query: select relname, reldiststyle pg_class how many rows should specify? it depends on cluster size using. diststyle copy data of table nodes - mitigate data transfer requirement across nodes. can find out size of table , redshift nodes available size, if can afford copy table multiple times per node, it! also, if have requirement of joining other tables table very frequently, in 70% of queries, believe worth space if want better query performance. if join keys across tables same in terms of cardinality, can afford distribute tables on key similar keys lie in same node obviate replication of data. i suggest trying out 2 options above, , comparing average query run times of around 10 queri

i sending struct in binary format c python script. my c struct: struct example { float val1; float val2; float val3; } how send it: struct example *ex; ex->val1 = 5.3f; ex->val2 = 12.5f; ex->val3 = 15.5f; write(fd, &ex, sizeof(struct example)); how recieve: buf = sock.recv(12) buf = struct.unpack('f f f', buf) print buf but when print out on python side random garbage. i'm pretty sure there wrong struct definition in python i'm not sure what. this line wrong: write(fd, &ex, sizeof(struct example)); it should be: write(fd, ex, sizeof(struct example));

i have dictionary in main sub (key = string; value = class object). class object consists of 2 dictionaries. collect data , check values stored in dictionary values (class object - dictionaries) noticed last values getting stored. mean values in dictionary in main sub pointing same dictionary reference, hence, instances of class objects contain same data. means need make clone of class objects (deep copy?). have done before class objects stored simple values, not dictionaries. need cloning class object contains dictionaries. main sub dim dgroup new scripting.dictionary ' main dictionary ' ' loop thru listbox = 0 userform1.listbox1.listcount - 1 gname = userform1.listbox1.list(i) ' listbox names ' populate temp dictionary set dic = fnc.get_session_file_elements(mysesfile, gname) ' ' instantiate new class object dim newcol new cvm_col call newcol.init(dic) ' pass dictionary 'constructor' dgroup.add gname, newcol.clone

i'm using objects improperly somehow. basically, want: angular.module('mobiledashboardapp') .directive('localforagemodel', function ($localforage) { return { link: function postlink(scope, element, attrs) { scope.$watch(attrs.ngmodel, function () { $localforage.setitem(attrs.localforagemodel, scope[attrs.ngmodel]); console.log(attrs.ngmodel); console.log(scope[attrs.ngmodel]); console.log(scope.user.companyid); console.log(scope["user.companyid"]); }); } }; }); to output user.companyid dsf dsf dsf instead of current output is: user.companyid undefined dsf undefined can point me in right direction? or suggest better title this? you have incorrect notation, must be var props = attrs.ngmodel.split("."); scope[props[0]][props[1]] as dot notation

is there way display different small image (icon) each row of nstablecolumn ? i don't need add new column it, wondering if can add icon in front of text of each row. i know there method: - (void)setdatacell:(nscell *)acell . method seems use same cell rows, not want. is there solution problem doesn't require subclass nstablecolumn ? if not, should subclass ? thanks make cell column in question nsimagecell. can in interface builder dragging "image cell" object library onto column. select column , you'll able bind image source via 1 of data, value, value path, or valueurl bindings. 1 choose depends on whether source property in model returns nsdata, nsimage, nsstring path, or nsurl url, respectively. see documentation on nsimagecell bindings more complete information. cells same each row, because they're lightweight class used performance optimization drawing. doesn't mean each row has use cell draw same image though, more text colu

i had code crunched lot of data, started on thursday , left running on weekend. on monday, have come , seen finished. used stopwatch function track length of time code ran for. however, ended elapsed: 2.18:57:55.xxx i understand it's output h:m:ss, don't understand first digit, since it's been running days. did convert hours days? did leave running long broke? edit: sorry, didn't mean finished on monday. meant monday (when returned computer), done. yes - that's format of timespan.tostring : the returned string formatted "c" format specifier , has following format: [-][d.]hh:mm:ss[.fffffff] elements in square brackets ([ , ]) may not included in returned string. colons , periods (: and.) literal characters. non-literal elements listed in following table. note string returned tostring() method not culture-sensitive. since there's not format specifier shows total hours, you'll need calculate it. if want hours sh

according json.net documentation ienumerable types should serialized json array. so expect following class: public class myclass { public ienumerable<string> values { get; set; } } to serialized as: { "values": [] } the problem when use typenamehandling=auto get: { "values": { "$type": "system.string[], mscorlib", "$values": [] } } i need typenamehandling=auto other properties expect ienumerable use default serialization. other types ( ilist example) works expected. it bug or missing something? here full code reproduce problem: [test] public void newtonsoft_serialize_list_and_enumerable() { var target = new newtonsoft.json.jsonserializer { typenamehandling = typenamehandling.auto }; var myevent = new myclass { values = new string[0] }; var builder = new stringwriter();
